All core development and bundled +plugins are required to be in this format. Plugin developers are strongly +encouraged to adopt these standards. + +* Unix line endings. + +* Hard tabs, 4 character tab spacing. + +* No PHP shortcut tags ( <? or <?= or <% ). + +* PHPDoc comments on functions and classes (all methods; declared properties + when appropriate). + +* Mandatory wrapped {}s around any code blocks. + Bad: + if (true) + foreach($arr as $elem) + echo $elem; + + Good: + if (true) { + foreach ($arr as $elem) { + echo $elem; + } + } + +* Name standalone functions using underscore_character(). + +* Name classes using CamelCase() and methods using lowerCamelCase(). + +* Name globals and constants in ALL_CAPS (ACCESS_FRIENDS, $CONFIG). + +* Use underscores / camel case to separate standard English words in + functions, classes, and methods. (get_default_site(), ElggUser->isLoggedIn()). + +* Space functions like_this($required, $optional = TRUE). + +* Space keywords and constructs like this: if (FALSE) { ... }. + +* Correctly use spaces, quotes, and {}s in strings: + Bad (hard to read, misuse of quotes and {}s): + echo 'Hello, '.$name."! How is your {$time_of_day}?"; + + Good: + echo "Hello, $name! How is your $time_of_day?"; + +* Line lengths should be reasonable. If you are writing lines over 100 + characters on a line, please revise the code. + +* Use // or /* */ when commenting. + +* No closing PHP tag (?>) at EOF unless after a heredoc. (Avoids problems with + trailing whitespace. Required after heredoc by PHP.) |
